Bio-SAC-A
Anticorrosion. Industrial anti-corrosion coating for exterior metal exposed to weather and UV

Bio-SAC-A is a premium, two-component (2K) industrial coating engineered for the most aggressive exterior environments. By fusing a high-performance bio-based resin matrix with the extraordinary barrier properties of graphene, this coating provides a molecular-level shield against oxidation, moisture, and extreme UV radiation.
ADVANCED TECHNOLOGIE
- 2K Bio-Hybrid Matrix: A high-solid, two-component system derived from renewable biomass. This provides the chemical resistance of industrial polyurethanes with a significantly lower carbon footprint.
- Graphene Molecular Barrier: Graphene flakes create a “tortuous path” for corrosive agents. This nanometric mesh prevents H2O, O2, and chlorides from reaching the metal substrate, effectively halting the electrochemical process of corrosion.
- UV-Shield Technology: Advanced light stabilizers and the natural opacity of graphene protect the polymer chain from photo-degradation, ensuring the coating does not chalk or peel under intense sunlight.
- Active Passivation: Formulated to passivate the metal surface, creating a stable oxide layer that prevents the spread of $Fe_2O_3$ (rust) even if the coating is mechanically damaged.
KEY FEATURES
- C5-Industrial Grade Protection: Engineered to meet the highest corrosivity categories, making it suitable for coastal, marine, and heavy industrial zones.
- Enhanced Adhesion: The 2K chemical cure ensures a superior bond to carbon steel, galvanized steel, and aluminum.
- Thermal Stress Resistance: Graphene’s high thermal conductivity allows the coating to dissipate heat evenly, reducing the mechanical stress caused by rapid temperature fluctuations (expansion and contraction).
- Eco-Efficient: Low VOC content and bio-sourced components make it the ideal choice for projects with strict environmental regulation
- Class 1 scrub resistance (EN 13300) ASTM D2426 (>10.000 cycle)
- Excellent corrosion protection
- UV stability
- Prevents condensation
- Free from VOCs and formaldehyde emissions
- Organic content < 5%
COMPETITIVE ADVANTAGES
- While standard industrial primers rely on heavy metals like Zinc for protection, Bio-Graphene 2K-Metal uses the physical “impenetrability” of graphene. This allows for a thinner, lighter coating that provides superior protection without the toxic profile of traditional heavy-duty paints. It is the only 2K system that successfully balances “Heavy-Duty” performance with a “Bio-Base” philosophy.
